Qld A-G seeks advice on slasher's sentence

Queensland's attorney-general is seeking advice on the sentencing of a man who sliced off a part of his ex-girlfriend's tongue during a 2010 attack.

Mohammed Tasleem Tahir was sentenced to a maximum eight-and-a-half years' jail in Southport Magistrates Court earlier this month after pleading guilty to charges arising from the attack.

Tahir, from Adelaide, was convicted of grievous bodily harm for beating his ex-girlfriend with a bottle, slashing her mouth and severing her tongue.

Judge Katherine McGinness ruled the 23-year-old would be eligible for parole from September 12 next year, taking into account the 703 days he had already spent in custody, his youth and the lack of a previous violent criminal history.

Queensland Attorney-General Jarrod Bleijie said on Thursday he was asking for advice on whether the sentence can be appealed on the grounds it is manifestly inadequate.

Mr Bleijie said the sentence "does not set an adequate deterrent" and isn't in line with the expectations of the community as a penalty for such a serious offence.
